Class
    Foam::mappedVelocityFluxFvPatchField

Description
    This boundary condition maps the velocity and flux from a neighbouring
    patch to this patch.

Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | flux field name         | no          | phi
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            mappedVelocityFlux;
        value           uniform (0 0 0);
    }
    \endverbatim

    This boundary condition can only be applied to patches that are of
    mapped type.
